training grip may
have a U-shaped bottom surface and a substantially flat upper surface.
[0007] According to an aspect, the gripping area may include a non-
dominant hand
gripping area and a dominant hand gripping area, where the upper surface of
the non-
dominant hand gripping area is angled away from the target area and the upper
surface of the
dominant hand gripping area is angled toward the target area. The
substantially flat upper
surface of the non-dominant hand gripping area may be angled away from the
target area at an
angle of between 2¨ 10 degrees and the substantially flat upper surface of the
dominant hand
gripping area is angled toward the target area at an angle of between 5 ¨20
degrees.

while using the golf swing training club.
DETAILED DESCRIPTION
[0020] A golf swing training club generally identified by reference
numeral 20, will now
be described with reference to FIG. 1 through FIG. 11.
[0021] Referring to FIG. 1A and 1B, golf swing training club 20 for
training a golfer has a
shaft 22. Shaft 22 has a club head 26 with a club face 28 for striking the
ball at a first end 21
of shaft 22. Training club 20 is shaped similarly to other clubs and has a
club head 26 similar
to other club heads on regular golf clubs. As can be seen club head 26 extends
out from shaft
22 in a first direction and club face 28 faces in a second direction that is
generally
perpendicular to the first direction. Referring to FIG. 2A, club face 28 has a
flat surface used
for striking the golf ball 30 which, if hit correctly, should travel in the
intended path of the
ball 32 towards a target area 34 in the second direction and toward a target
area. Preferably,
training club 20 is used on clubs that generally use a full swing, such as
drivers, woods,
hybrids, irons, wedges, etc. and not generally a putter. For training
purposes, training club 20
is preferably an iron. In general, the types of clubs contemplated to be used
with training club
will have a club face with a loft of between 5 and 65 degrees relative to the
shaft, although
other lofts may also be used.
20 [0022] Referring again to FIG. 1A and 1B, shaft 22 has a gripping
area 49 at a second end
24 of shaft 22. In this description, first end 21 is considered to be the club
end and will be
described as below second end 24, or the grip end, as this is the orientation
of the club in use.
Preferably, gripping area 49 has a dominant hand gripping area 50 and a non-
dominant hand
gripping area 60. Gripping area 49 may have a known type of grip, or may have
a different
type of grip to enhance the training aspects of club 20, as will be described
in more detail
below.
[0023] Club 20 also has a training grip 70 to be gripped by the dominant
hand of the user.
Training grip 70 is carried by shaft 22 and is positioned above shaft 22 in
the direction of
club head 26 (i.e. perpendicularly away from the axis of shaft 22) and
adjacent to and below
gripping area 49 relative to club head 26. Referring to FIG. 4A and 4B,
training grip 70 is
positioned such that, relative to a direction from second end 24 toward first
end 21 of shaft 22,
CA 02866928 2014-09-10
WO 2013/134872
PCT/CA2013/050182
training grip 70 is angled away from shaft 22 toward a point that is spaced
from first end 21 of
shaft 22 in each of the first and second directions. In other words, when club
20 is held by the
user in the normal golfing stance, referring to FIG. 2A, training grip 70 will
be above shaft 22
and angled toward the target area 34, such that the user's dominant thumb is
above the club
5 and pointing toward the target area 34. Referring again to FIG. 4A - 4C,
preferably, training
grip 70 is angled away from shaft 22 between 20 and 45 degrees in the first
direction and
between 20 and 50 degrees away from shaft 22 in the second direction. Training
grip 70 is
also preferably spaced downward from the non-dominant gripping area 60 far
enough that the
user must move the dominant hand toward club head 26 in order to grip training
grip 70
relative to the normal dominant hand position on grip area 49. As training
club 20 is designed
to be used with training grip 70, it may not be necessary to have a dominant
hand grip 50, as
this will not be used when the dominant hand is gripping training grip 70.
However, it is
preferred to also have dominant hand gripping area 50 as it increases the
functionality of club
as it allows club 20 to be used with a regular swing, and also allows a
training grip to be
15 provided to help users learn a proper grip. It will be noted that
whether dominant hand grip
50 is present or not will not affect the preferred position of training grip
70 along shaft 22.
[0024] Training grip 70 may be permanently attached to shaft 22, or it
may be removably
attached to shaft 22. FIG. 2A and 2B show a removable training grip attached
by a two-part
connector, where, referring to FIG. 2B, training grip 70 has a first part 80
of the connector
20 located at one end of training grip 70 and shaft 22 has a second part 82
of the connector
located below the gripping area 49. The actual position of first and second
parts 80 and 82
may vary, depending on the design of the connectors and club 20. FIGS. 1A and
1B depict
club 20 in an embodiment where training grip 70 is attached to club 20 with
first part of
connector 80 connected to second part of connector 82, locking training grip
70 into place.
While a two-part connector is depicted in the drawings, training grip 70 may
be attached to
shaft 22 using a clamp, a clasp, a latch, or any other known type of
attachment. Alternatively,
training grip 70 may be attached to shaft 22 in such a way that it is
collapsible relative to shaft
22, where training grip 70 is permitted to pivot until it is aligned with
shaft 22 and then
lowered relative to shaft 22 to allow for easier storage of club 20, or to
reduce the risk of
training grip 70 interfering with a normal swing.
[0025] FIGS. 8A - 8F illustrate six different stages of the swing of a
golfer using a
CA 02866928 2014-09-10
WO 2013/134872
PCT/CA2013/050182

traditional golf club and FIGS. 9A ¨ 9F illustrate six different stages of the
swing of a golfer
using club 20. The golf swing depicted in FIGS. 8A - 8F and the golf swing
depicted in FIGS.
9A - 9F are both described by stages below.
[0026] Both golf swings begin with the address stage 100 shown in FIGS.
8A and 9A. The
golfer then begins their backswing and moves to the set stage 102, shown in
FIGS. 8B and
9B, which is part way through the back swing. FIGS. 8C and 9C depict the top
stage 104 with
the club head at the top of the backswing. The golfer then begins their down
swing and part
way through the down swing is the lag stage 106 as depicted in both FIGS. 8D
and 9D. FIG.
8E and 9E depict the impact stage 108, which includes the moment of contact
between club
face 28 and golf ball 30. The final stage of the golf swing is the release
stage 110 which
occurs when club face 28 is released and the forearms cross over on one
another depicted in
FIGS. 8F and 9F. After this, the golfer's head snaps upward in the finish
stage (not shown).
[0027] FIG. 10 illustrates all six stages of a golf swing using a normal,
or ideal, golf
swing. The six stages shown are: address 100, set 102, top 104, lag 106,
impact 108, and
release 110. The travel and the orientation of club face 28 throughout all six
stages of the golf
swing. During the normal golf swing, the dominant and non-dominant hands of
the golfer are
in contact with each.
[0028] The normal golf swing is a representation of the ideal swing or
movement
sequence of club head 26 and the golfer's body. However, this golf swing is
difficult,
complicated, and also requires a much faster swing motion by the golfer (i.e.
progression
through the six stages) in order to execute this golf swing correctly as
compared to a training
swing depicted in FIG. 11 using training club 20. It should also be noted that
the path of club
head 26, shown by curved line, travels in a larger arc in the normal swing of
FIG. 10
compared to the smaller arc of the curved line of the training swing depicted
in FIG.11.
[0029] Referring to FIG. 10, starting at address 100, club head 26 is
moving inside (i.e.
closer to the golfer) to set 102, at which point club head 26 transitions
outside (i.e. further
from the golfer) until, just before club 20 is parallel or horizontal, it
transitions inside again
and reaches top 104. Then club head 26 transitions back outside for a short
distance before
transitioning back inside just before reaching lag 106. From the beginning of
lag 106 until just
before impact 108, club head 26 transitions outside. Club head 26 remains
outside for the
remainder of the swing to and beyond release 110.

[0030] FIG. 11 illustrates all six stages of a golf swing using club 20.
The six stages
shown are: address 100, set 102, top 104, lag 106, impact 108, and release
110. The curved
line in FIG. 11 also depicts the path of travel and the orientation of club
face 28 throughout all
six stages of the golf swing with club 20. During the golf swing with club 20,
the dominant
and non-dominant hands of the golfer are not in contact with each other
throughout the entire
swing.
[0031] The training golf swing of FIG.11 is slower, easier, and
relatively simple compared
to the swing in FIG.10. During a training golf swing using club 20, club head
26 travels
through an inside sequence (i.e. closer to the golfer) from address 100
through set 102 and
moving to top 104. Club head 26 then moves outside (i.e. further from the
golfer) from top
104 through lag 106, impact 108, and release 110. It should also be noted that
the path of club
head 26 travels in a smaller arc in FIG. 11 compared to the larger arc of the
swing depicted in
FIG.10. At no point during the swing in FIG. 10 or the swing with club 20 in
FIG. 11 does the
path of club head 26 cross over or under the curved line on the way to top 104
or from the top
104 to impact 108. Club head 26 follows an inside then outside movement
sequence during
both swings. It should be noted that club head 26 is closer to the golfer's
body at release 110
compared to release 110 using the normal swing illustrated in FIG.10.
[0032] As mentioned above, club 20 may also be designed to train a user
to improve their
grip. In one example, referring to FIG. 5A, 5B and 5C, non-dominant hand grip
50 and
dominant hand grip 60 may have U-shaped cross-sections with a flat upper
surface where the
thumb is generally placed. Referring to FIG. 5A, non-dominant hand grip 50 and
dominant
hand grip 60 have areas for the correct placement of the golfer's thumbs. In
one example,
non-dominant hand gripping area 50 has a non-dominant hand thumb placement pad
54 and
dominant hand gripping area 60 has a dominant hand thumb placement pad 64.
This guides a
user to a proper hand position on gripping area 49, with the understanding
that, with proper
thumb placement, the fingers will follow. In addition to thumb pads, the grip
may be shaped
or marked in other ways to help guide the finger position of the user, such as
with lines to
show thumb and/or finger position, or bumps and grooves to urge thumb, finger
and/or heel of
the hand into the proper position. Referring to FIG. 6A, the training grip 70
may also have a
training grip thumb placement pad 74. In addition to proper thumb and finger
position, the U-
shaped cross section of each of the grips 50 and 60 may be angled relative to
each other to
CA 02866928 2014-09-10
WO 2013/134872
PCT/CA2013/050182

ensure a proper or exaggerated overlap between the hands. As shown, referring
to FIG. 5B,
the upper surface of non-dominant hand grip 50 may be angled away from the
target area 34
(shown in FIG. 2A), or clockwise from the top of the grip at an angle of, for
example, 2 to 10
degrees while upper surface of the dominant hand grip 60 is angled towards the
target area 34,
or counter-clockwise from the top of the grip at an angle of, for example, 5
to 20 degrees.
[0033] In another example, the various gripping areas may have tapers and
contours
along the axis to help improve the user's grip of the club. As shown in FIG.
6A and 6B,
gripping area 49 has a non-continuous taper between non-dominant hand section
50 and
dominant hand gripping area 60. As can be seen, dominant hand gripping area 60
has a
reverse taper, i.e. it gets larger moving down the grip, while the non-
dominant hand gripping
area 50 has a relatively continuous, gradual taper at the top end that
develops a sharper slope
as it joins with dominant hand gripping area 60. As shown in FIG. 6A, training
grip 70 may
also have a reverse taper.
[0034] FIG. 3 is an exploded view of the golf swing training club. The
club head 26 which
has a club face 28 is attached to the shaft 22 at a first end by a hosel 25.
The shaft extends
towards a second end 24 that has a gripping area 49 which has a dominant hand
gripping area
60 and a non-dominant hand gripping area 50. The gripping area has areas
specifically for the
correct placement of the golfer's thumbs. The non-dominant hand gripping area
50 has a non-
dominant hand thumb placement area 52 underneath a non-dominant hand thumb
placement
pad 54. The dominant hand gripping area 60 has a dominant hand thumb placement
area 62
underneath a dominant hand thumb placement pad 64. The first end of the shaft
22 has a shaft
bolt 46 that may be designed with sufficient weight to act as a counterweight
which helps the
golfer have the correct backswing motion of their golf swing. Those skilled in
the art will be
able to determine an appropriate weight ratio between the club and the
counterweight to
achieve the desired result. The shaft bolt 46 extends through the
counterweight cap connector
44 and connects the shaft 22 to the counterweight cap 42 which is located at
the second end of
the golf swing training club 20.
[0035] In FIG. 3, the first part of connector 80 at the end of the
training grip shaft 78
attaches to the second part of connector 82 which is exposed through a hole
near the first end
of the dominant hand gripping area 60. The second part of connector 82 is
attached to the
second part of connector housing 88 which encircles a part of the shaft 22
underneath the
CA 02866928 2014-09-10
WO 2013/134872
PCT/CA2013/050182
9
dominant hand gripping area. The second part of connector housing also
contains a connector
spring 86 which is covered by a connector button 84. In one example, the
golfer pushes down
on the connector button 84 and slides the training grip 70 towards the first
end to detach the
training grip. In the same example, the golfer would line up the first part of
connector 80 of
the training grip 70 below the second part of the connector 82 and slide the
training grip in the
direction of the second end of the golf swing training club until the training
grip is locked in
place by the connector button 84 through a hole in the first part of connector
80. The training
grip shaft 78 is enveloped by the training grip 70 which extends away from the
first part of
connector 80 and after a curved part has a training grip raised area 76 which
is shaped in such
a way as to mimic the thumb of the non-dominant hand of the golfer. The
training grip also
has a training grip thumb placement pad 74. In the depicted example, the
training grip is
designed to be gripped in such way that the thumb of their dominant hand is on
the training
grip thumb placement pad 74. The end of the training grip 70 that is away from
the first part
of connector 80 has a training grip cap 72.
[0036] FIGS. 4A and 4B depict second end 24 of the golf swing training club
including
the non-dominant hand gripping area 50 and the dominant hand gripping area 60
on the shaft
22 and the training grip 70 which is attached to shaft 22 below the dominant
hand gripping
area 60. In full-swing mode, the golfer places the thumb of their non-dominant
hand on the
non-dominant hand thumb placement pad 54 and the thumb of their dominant hand
on the
dominant hand thumb placement pad 64 after they have the correct grip club 20.
In training
mode, the golfer places the thumb of their non-dominant hand on the non-
dominant hand
thumb placement pad 54 and the thumb of their dominant hand on the training
grip thumb
placement pad 74. The training grip is angled in the direction of the target
area 34 (shown in
FIG. 2A), such that the angle between the axis of the shaft 23 and the axis of
the training grip
79 is 20 to 50 degrees as shown in FIG. 4A. Referring to FIG. 4B, the training
grip is angled
away from the shaft in the direction of the club head, such that the angle
between the axis of
the shaft 23 and the axis of the training grip 79 is 20 to 45 degrees. The
combination of the
angles shown in FIG. 4A and FIG. 4B determine the orientation of training grip
70 relative to
shaft 22.
[0037] In this patent document, the word "comprising" is used in its non-
limiting sense to
